Randomly Disconnecting Losing Maps While in the stash

Reference ID: 4,231,580,809
The system lags a little, so I'm either kicked out or it takes a few seconds to run. Yesterday, I did a map and used the scroll to teleport to my base. After I arrived and sold some items to the vendor, I was disconnected. The map and the items in my inventory were gone when I logged back in. I logged in today and ran two maps before I had an issue. I used the portal to travel to my hideout, sell some items, and put some in my stash, but the portal is no longer there. I logged out and back in, and it still doesn't show the map.
